Corrigendum to: "Ultrasound Guided Wire Localization of Anal Tract in Imperforate Anus"

We have completed the study entitled “Ultrasound Guided Wire Localization of Anal Tract in Imperforate Anus” by Alamdaran et al. published in the Iran J Pediatr 2018; 28(4): e65338(1). Wewould like to add some commentary to it. Continence in patients with imperforate anus is related to exact anus reconstruction from middle of sphincter complex. We designed this study with purpose to investigate the ability of ultrasound in detection of the location and pathwayof sphinctermuscle complex in childrenwith Imperforate Anus. Our ultrasound findings in this study included (1) concentric multi-layered structures in subcutis (probably anal pit). (2) Concentric multi-layered structures in depth of pelvic floor (probably anal sphincter complex). (3) Difference in distance of rectal pouch and the surface of skin through probably anal pit and anal sphincter complex pathway with the shortest distance. (4) The ability to differentiate the types of internal fistula.
